Calm down, yo mama; there's no need to shout. And it's not true that haikus exclusively depict detailed scenes. After all, how much actual detail can you squeeze into 17 syllables? From what i've read and know, most haiku do contain some description of nature, but the main aim is to convey an emotion, idea or philosophical point.

LET ME GET THIS STRAIGHT. HAIKUS DEPICT A DETAILED SCENE. IT IS NOT GENERAL POETRY.
